本文应用超声多普勒体外测量门脉血流及超声引导下插管测定门静脉压的方法计算门脉高压症患者的门脉血管阻力.对60例慢性肝病患者及5名正常对照者的测定结果为:门脉血管阻力对照组:0.25±0.13mmHg·ml~(-1)min·kg;慢性活动性肝炎组:0.64±0.29mmHg·ml~(-1)min·kg;肝硬化组:1.34±0.79mmHg·ml~(-1)·min·kg;特发性门脉高压组:0.85±0.69mmHg·ml~(-1)·min·kg.方法:超声引导下经皮肝穿刺至肝内门静脉分支,换置5F导管,导管尖插至门静脉主干.经股静脉插入7F带气囊导管到肝静脉,气囊充气阻塞肝静脉分支,测肝静脉楔压.门脉压(P_(PV))及肝静脉压(P_(HV))均显 In this paper, portal vein blood flow in patients with portal hypertension and portal hypertension in patients with portal hypertension were measured by measuring the portal blood flow with ultrasound Doppler in vitro and intubation under ultrasound guidance.Results of 60 patients with chronic liver disease and 5 normal controls As follows: portal vein resistance control group: 0.25 ± 0.13mmHg · ml -1 min · kg; chronic active hepatitis group: 0.64 ± 0.29mmHg · ml -1 min · kg; cirrhosis group: 1.34 ± 0.79mmHg · ml -1 · min · kg, and the incidence of idiopathic portal hypertension was 0.85 ± 0.69mmHg · ml -1 · min · kg.Methods: Percutaneous transhepatic puncture of the liver The branch of the portal vein was replaced by a 5F catheter inserted into the main portal vein.The 7F balloon catheter was inserted into the hepatic vein via the femoral vein and the balloon was inflated to block the branch of the hepatic vein and measure the hepatic venous wedge pressure.Portal pressure (PV) And hepatic venous pressure (P_ (HV)) were significantly
